Intake of a fermented plant product attenuates allergic symptoms without changing systemic immune responses in a mouse model of Japanese cedar pollinosis

Japanese cedar pollinosis (JCP) is one of the most prevalent allergies in Japan. Within the past few decades, many food factors have been demonstrated to suppress symptoms of pollinosis and mast cell degranulation directly or indirectly. Herein, we conducted a study to clarify the anti-allergic pote...

Description
Summary:Japanese cedar pollinosis (JCP) is one of the most prevalent allergies in Japan. Within the past few decades, many food factors have been demonstrated to suppress symptoms of pollinosis and mast cell degranulation directly or indirectly. Herein, we conducted a study to clarify the anti-allergic potency of a fermented plant product (FPP) in JCP model mice. Mice were administered FPP, 10-fold-diluted FPP, or saline every day for 40 days by oral gavage and sensitized with major Japanese cedar pollen allergens (SBP). The numbers of sneezes were counted for 5 minutes after SBP nasal challenge. We analyzed the SBP-specific immunoglobulin titers, serum concentration of mast cell protease 1, and cytokine production from splenocytes stimulated with SBP. The numbers of sneezes by the mice administered FPP were significantly suppressed compared to those administered saline. The 10-fold-diluted FPP also suppressed the number of sneezes compared to saline, although not significantly. Serum level of mast cell protease 1 tended to be suppressed in FPP-consumed mice compared to those in saline-treated mice. The SBP-specific immunoglobulin titers and cytokine production were comparable among the groups. Our results suggest that FPP intake could attenuate JCP symptoms without change of systemic immune responses.
